what are they ?
i know they are related to quantum theory.

Why explain shortly and possibly misinterpret when YOU can read?

I'm impressed. Thanks for the link. It is Hardy's original article, only 34 pages, and gives the 5 axioms
http://arxiv.org/quant-ph/0101012 [Broken]
In the quantum case, with K = N^{2} , we have thatCentral to the axioms are two inte-
gers K and N which characterize the type of system
being considered.
* The number of degrees of freedom, K, is defined
as the minimum number of probability measure-
ments needed to determine the state, or, more
roughly, as the number of real parameters re-
quired to specify the state.
* The dimension, N, is defined as the maximum
number of states that can be reliably distinguished from one another in a single shot measurement.
We will only consider the case where the number
of distinguishable states is finite or countably infinite. As will be shown below, classical probability theory has K = N and quantum probability theory has K = N^{2} (note we do not assume that states are normalized).
i agree with you.Originally posted by marcus
I wouldnt always want to start downloading a PDF file from arxiv without first
looking at the abstract. Some articles have hundreds of pages.
And the title and brief summary can sometimes tell you enough. Here is the abstract for what Paden recommends reading. If you like the short summary in the abstract then click on "PDF" button right below it.
